The deterioration of neurologic symptoms, like disc rupture or cauda equina syndrome within short time caused by abdominal pressure, seems to be an uncommon event. We experienced a man who had a sudden deterioration to cauda equina syndrome for a day. We presume that the reason is the increase of abdominal pressure by coughing. He had also undergone to repetitive minute damage after degenerative condition. Therefore, doctors and patients should be aware about degenerative state, possibility of minute damage, and be careful to its cause like coughing.

To select agronomically useful transgenic plants, a large number of transgenic events are initially produced, gene transfer confirmed, and advanced to obtain homozygous lines for testing in field trials. Direct in planta assays for identifying the transgene carriers in the segregating progeny are based on the activity of selectable marker gene and are easy, simple and inexpensive. For this purpose, expression of bar gene as measured by tolerance to damage by glufosinate ammonium, the active ingredient in the herbicide BASTA, was investigated. Dose damage curves were generated by leaf paint tests with BASTA on four genotypes of sorghum. Transgenic plants were characterized in terms of sensitivity to the concentration of glufosinate ammonium. In transgenics, symptoms of BASTA swab tests at different growth stages and PCR analysis for cry1B were carried out and correlated. Germination tests could not be employed for large scale evaluation of transgenic progeny because of mortality of tolerant seedlings after transplantation to soil. Based on the above findings, a simple, inexpensive, time-saving, two-step scheme for effective evaluation of transgenics and their progeny containing bar gene as selection marker using BASTA swab tests is described.

Delayed onset muscle soreness (DOMS) is a painful condition that arises from exercise-induced muscle damage after unaccustomed physical activities. Various therapeutic interventions have been applied to reduce the intensity and duration of DOMS-related symptoms. Recently, pulsed electromagnetic field (PEMF) intervention has been introduced as an alternative noninvasive treatment for DOMS. This randomized, double-blind, placebo-controlled experiment was conducted to examine the effects of PEMF therapy on DOMS in elbow flexors at 24, 48, and 72 hours after the experimental DOMS induction. Thirty healthy volunteers ($23{\pm}2.4$ yrs, $175{\pm}5.7$ cm, and $74{\pm}7.8$ kg) participated in this study. Each was randomly assigned to a PEMF or placebo group. On the first day, DOMS was induced in the elbow flexors by repeated isokinetic motions at low ($60^{\circ}/s$) and fast ($120^{\circ}/s$) speeds in all subjects. Thereafter, the PEMF group received 15-min daily treatment with a PEMF device. The placebo group received sham treatment of the same duration. Overall, PEMF application was more effective than the sham treatment in reducing the physiological symptoms associated with the DOMS including perceived soreness, median frequency, and electromechanical delay of the surface electromyography. In addition, median frequency and isokinetic peak torque of the PEMF group recovered to the pre-DOMS induction level earlier than the placebo group. In conclusion, this study suggests that PEMF can be applied as a new recovery strategy in reducing DOMS symptoms. Further experiments are required to examine the effect of the PEMF treatment on different types of exercise conditions and to determine the optimal treatment dosage and duration in a real clinical setting.

Since the peculiar virus disease of chinese date tree (Zizyphus jujuba Mill. var. inermis Rehd.) has been noted in South Korea around 1950, 70% to 80% of the economically important trees have been either completely destroyed or infected with the virus, severe damage has been noted, particularly, across the area ranged from middle east to the middle part of Korea, including Seoul area. Yoon-Koock-Byung in 1958 first reported the disease and descirbed it might be caused by a kinds of yellows. But he did not conform in his paper that the disease is pecisely caused by yellows virus. The authors, hereby intend to identify the true cause of the desease of the chinese data tree by studying the external symptoms of the disease and the internal morphological characteristics of the diseaset plant which shows various abnormalities in contrast to the healthy checks. In view of fact that leaves of the infected plants become yellowish in color similar to the peach yellows, aster yellows, it is likely to be identifiable as the common yellows. Furthermore, the abnormal characteristics observed by the authors are as follow: The floral organs such as petals, sepals, stamens, and pistil turn into vegetative leaves, the leaves on heavily infected plant appear as small sized one and also showing as a common witch's broom like symptom. There are also an occuring of numerous advantitious shoots developed from both of stems and roots. The amount of photosynthetic starch grains increases in parenchymatous cells, necrosis takes place in mesophyll, Particularly, Palisade Parenchyma in the leaves of infected plants are distinguished in contrast to the healthy checks. From the symptoms and the present experimetns described above, the authors are believed that the disease of chinese data tree is not caused by the yellows. It appears the disease is rather similar to the symptoms of sandal spike virus which was noted in India early in this centry. But the host plant of standal disease, Santalum albun L. and the insect vector, Jassus indicus Wal., have never been reported in Korean flora and the founa. The termperature and the otehr environmental factors is quite different Korea and India. Thus the authors believe that the peculiar disease must be an endemic new virus origin in Korea and must be called as "shoot cluster disease of chinese date tree."

Purpose: This study aims to assess the psychological characteristics of patients with iatrogenic damage of the trigeminal nerve using Symptom Checklist-90-Revised (SCL-90-R). Methods: A total of 22 patients who visited the clinic of Department of Oral Medicine, School of Dentistry, Chosun University were evaluated in the months from December 2012 to December 2014. Patients were included in the study if they presented with reported sensory changes due to iatrogenic trigeminal nerve injury. A total of 37 control group who has no symptoms of pain and sensory change were included in the study. All participants filled out the SCL-90-R instrument to assess psychosocial symptoms. Results: The T-scores of most of the SCL-90-R symptom dimensions were within normal range (less than 55) in the patients and the control group. The patients group showed higher T-scores of SCL-90-R than those of the control group, with statistically significance of somatization, anxiety, psychoticism, and positive symptoms distress. Female patients group had higher Tscores of SCL-90-R than those of male patients group, but there was no statistical difference, except for the positive symptom global index. The chronic patients group showed higher Tscores of SCL-90-R than those of the acute patients group, but there was no statistical difference, except for the Positive symptom global index. Conclusions: According to the psychological assessment of iatrogenic trigeminal nerve injury patients using SCL-90-R, the patients group, as compared to the control group shows a significantly higher score for somatization, anxiety, and psychoticism. Therefore, assessment of psychological state would be considered to treat patients with iatrogenic trigeminal nerve injury.

Background: After tooth extraction, pain due to dry socket and pain in the adjacent tooth are common. The aim of this study was to retrospectively analyze pain in the adjacent tooth after surgical extraction of the mandibular third molar. Methods: Postoperative pain due to dry socket, pain in the adjacent tooth, and pain from other causes were present. Group A included patents with dry socket alone; group B included patients with pain in the adjacent tooth alone; and group C included patients with both. The duration of symptoms was recorded. In addition, the prognosis of pain was divided into the complete improvement, improvement, maintenance, deterioration, and complete deterioration groups. Results: A total of 312 mandibular third molars were extracted from 13, 60, and 10 patients in groups A, B, and C, respectively. The mean duration of symptoms was 5 days in group A and B and 15.2 days in group C. There were statistically significant differences in the duration of symptoms between groups A and C and groups B and C. Conclusion: Pain in the adjacent tooth after third molar extraction can be caused by inflammatory reactions and pressure on this tooth. The pain caused by pressure on the periodontal ligament and alveolar bone results from the cytokines released by osteoclasts, which are responsible for bone destruction. However, pain from periodontal ligament damage caused by excessive pressure may be misunderstood as pulpal pain. Unconscious parafunctional habits, such as clenching and bruxism, could also be associated with post-extraction pain.

Background: Instrument players are exposed to occupational musculoskeletal symptoms due to constant movement and strain to meet the needs of their audience. This can cause dissonance between the player and the instrument and can cause medical problems in the musculoskeletal system such as pain, tendinitis, muscle spasms, and joint hyperextension from overuse of body parts. Objective: The purpose of this study is to comparatively analyze the characteristics and occurrence of musculoskeletal symptoms in professional and student players, and to find out the awareness of the need for health care professionals and special exercise programs for orchestra players. Methods: The subjects were professional orchestral musicians 191 from the three symphony orchestras and music students 209 from the four universities volunteered to participate in this study; 393 subjects (98.25%) completed the questionnaire. symptom prevalence and related factors of playing-related musculoskeletal disorders (PRMDs) were surveyed with a self-administered questionnaire. Standardized Nordic Questionnaire was complemented by adding a visual-among scale and used to diagnose PRMD. Results: High prevalence of musculoskeletal complaints in both professional musicians (85.30%) and student musicians (82.30%). Professional musicians and student musicians also suffered the highest problem in shoulder and neck complaints. Significant differences were found between groups that recognized of necessity for specialized health professionals, professional organizations, and special programs for musicians. Conclusions: Professional musicians and student musicians, like orchestra players, are already exposed to overuse syndrome. However, student musicians lack awareness of the risk of injury compared to orchestra players. We suggest that an appropriate treatment management program for the prevention and early treatment of musculoskeletal system damage should be provided to performers at an early stage.

Objectives: Parkinson's disease is characterized by progressive, irreversible damage to dopamine neurons in the substantia nigra pars compacta, as well as motor and non-motor symptoms. This disease currently has no dependable disease-modifying treatment. In this paper, we describe the treatment of a 67-year-old female with Parkinson's disease using acupuncture and exercise therapy. Case Presentation: Clinical symptoms and the United Kingdom Parkinson's Disease Society Brain Bank Diagnostic Criteria were used to diagnose the patient with Parkinson's disease. Over a 12-week period, the patient visited a Korean medicine hospital 18 times and was treated with acupuncture and exercise therapy in addition to anti-Parkinson's drugs. Before and after treatment, clinical examinations were performed using tools such as the Unified Parkinson's Disease Rating Scale, Fall Efficacy Scale, Parkinson's Disease Questionnaire, Berg Balance Scale, and Non-Motor Symptoms Scale. Furthermore, functional near-infrared spectroscopy was used to assess cortical hemodynamics. All clinical examination results improved after 12 weeks of intervention. In particular, improvements on the Total Unified Parkinson's Disease Rating Scale and Part III of this scale demonstrated large, clinically important differences. Conclusion: This case suggests that combining acupuncture and exercise therapy could produce an effective treatment for Parkinson's disease patients.

The poultry industry, which produces excellent sources of protein, suffers enormous economic damage from diseases. To solve this problem, research is being conducted on the early detection of infection according to the behavioral characteristics of poultry. The purpose of this study was to evaluate the potential of a non-movement behavior observation method to detect sick chickens. Forty 1-day-old Ross 308 males were used in the experiments, and an isolator equipped with an Internet Protocol (IP) camera was fabricated for observation. The chickens were inoculated with Salmonella enterica serovar Gallinarum A18-GCVP-014, the causative agent of fowl typhoid (FT), at 14 days of age, which is a vulnerable period for FT infection. The chickens were continuously observed with an IP camera for 2 weeks after inoculation, chickens that did not move for more than 30 minutes were detected and marked according to the algorithm. FT infection was confirmed based on clinical symptoms, analysis of cardiac, spleen and liver lesion scores, pathogen re-isolation, and serological analysis. As a result, clinical symptoms were first observed four days after inoculation, and dead chickens were observed on day six. Eleven days after inoculation, the number of clinical symptoms gradually decreased, indicating a state of recovery. For lesion scores, dead chickens scored 3.57 and live chickens scored 2.38. Pathogens were re-isolated in 37 out of 40 chickens, and hemagglutination test was positive in seven out of 26 chickens. The IP camera applied with the algorithm detected about 83% of the chickens that died in advance through non-movement behavior observation. Therefore, observation of non-movement behavior is one of the ways to detect infected chickens in advance, and it appears to have potential for the development of remote broiler management system.
